Construction method for noise reduction type composite track board and noise reduction type composite track board
The invention provides a construction method for a noise reduction type composite track board and the noise reduction type composite track board, and belongs to the field of railway transportation. The construction method comprises the steps of S100, laying a track board body; S200, pouring sound absorption material on the track board body for forming a sound absorption layer, wherein the thickness of the sound absorption layer is no greater than the height of a track supporting table of the track board body. The height direction of the track supporting table and the thickness direction of the sound absorption layer are perpendicular to the board surface direction of the track board body. The noise reduction type composite track board is made through the construction method. The construction method for the noise reduction type composite track board is convenient and fast and lowers the construction cost. The sound absorption layer and the track board body are compact in structure, and the noise reduction effect of the sound absorption layer is better.
